Specification of Letters Patent.

Patented Nov. 19, 1912.

T0 all 107mm 1' t'may concern:

Be it known that I, Joan MOORES, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Machine for Molding Dough, of which the following is a specification.

The several features of my invention and the various advantages resulting from their use conjointly or otherwise, will be apparent from the following description and claims. J

In the accompanying drawings making a partof this specification, and in which similar characters of reference indicate corresponding part-s,Figure l is a plan view of a machine embodying my invention. Fig. 2 is a vertical central section of the said machine, this section being taken in the plane of the dotted line 2, 2, of Fig. 1. Fig. 3 is a vertical central section of a machine like that illustrated in Fi s. land 2, but modified so as to enable t-lie radii of the rotary devices for rolling and molding the dough to be in a vertical plane. Fig. 4 is a side elevation of that end of the mechanism shown in Fig. 3, which faces toward the right. In the plane of the dotted line 3, 3, of this figure, the section shown .in Fig. 3' is taken. Fig. 5 is a vertical section taken through the walls of the chamber in the plane of the dotted line 5, 5, of Fig. 1.

I will now describe my invention in detail. A is a disk concentrically mounted on a shaft B, capable of imparting a rotatory motion to this disk. The peripheral edge of this disk carries a flange A which latter extends at an angle from the plane of the disk. This angle is preferably about sixty degrees. This disk A also carries at its periphery a flange A extending at right angles to the plane of the said disk A. C is another disk mounted concentrically on a sleeve shaft D, capable of imparting a rotatory movement to this disk O. This disk C carries at its peripheral edge the flange C", at right angles to the disk C. To that edge of the flange G which is not connected to this disk C is connected an inclined flange is a stationary shell E. This shell has a bottom .(disk) E From the eripheral edge of this bottom E a side I upward, at right angles to said bottom E. This side E forms an annular shell and Outside of these flanges A and C 8 extendswall. At the outer edge of the inclined flange C 1s a flange C, preferably integral with flan'ge C and extended down verically as shown. This flange C bears against and is in. close proximity to the wall E The outer edge of the inclined flange A is 'provided with a vertical flange A which is close to the Wall E. The part A partA,

part C and wall' Effconstitnte'a chamber S, 7

preferably ,of nearly triangular .shape." in

cross section. At two places on the'pe'riphtherefrom, see Fig. 4. For a hopper, the

outer wall E is preferably formed with the pocket T, having side-walls T T and an inclined front or bottom T. For an exit chute, the outer wall 'E is preferably formed with the inclined bottom piece V extending out and down and with the side walls V V Suitable means for imparting a rotatory motion to the disk A and its flange A A A, constituting an entirety are provided. The preferred means is as follows: A shaft Bis concentrically fixed to the disk A. On the shaft B is a bevel gear wheel B feathered to the said shaft and capable of sliding thereon. A power shaft F is'present, and

this shaft F carries a bevel gear wheel F which latter engages with the gear wheel B and rotates the said ear wheel B and this in turn rotates the dlSk A and its parts A A, A. I provide suitable means for the rotation of the disk C and its flanged parts C C, C. The preferred means for carrying this object into effect is as follows: A sleeve D (through which extends said shaft B) carries a bevel gear wheel D Fixed on the power shaft F is a bevel ear wheel F that engages the gear wheel 2 and impartsrota-ry motion to the gear wheel D This'latter wheel D in turn rotates the said disk C. and its parts C, C, O.

The power shaft F is'sup orted by suitable bearings One kind of sdch bearings is shown in Fig. 2 and consists in a bearing sleeve EF located on one of the legs E which support the stationary frame E. The

other end of the shaft F is'journaled in a sleeve bearing E F and this is suit-ably supported, as for instance, as shown, by the sleeve E carried by cross brace E extending from a leg E to another leg E of the frame. This sleeve E is utilized asa collar support for the hub BH of the wheel B and this hub. BH in turn furnishes a convenient support for the sleeve D aforementioned. A

sleeve E fixed to the bottom E of the shell E extends down therefrom and outside of the rotatable sleeve D and comes into contact above with the hub of the bevel gear wheel D and-acts as a collar for the latter. 7

-Whe'n the piece of dough is placed in the chamber of the machine, it is desirable that the flange A of the disk A should not press upon thedough too heavily. If the said pieces of dough successively put into the chamber are not of exactly the same size and volume, the flange A in connection with the .disk A presses upon a large piece of dough more heavily than upon a smaller one.

Where the machine is constructed as shown in Fig. 2, the weight of the disk A and its parts A A, A and of the shaft B will ordinarily be too much for the elasticity of the roll of dough to overcome. Therefore to enable the roll of dough to lift the flange A and the disk A and overcome the weight of the said accompanying parts, I provide aspring G, and locate it directly beneath and against the lower end of the shaft B. I also provide'a set screw Hhaving a broad upper end H the latter located beneath the spring G and bearing against the latter.

2 The screw shank H of this set screw engages a screw thread in the bottom E of the sleeve E.

By rotating the handle H of this set screw H, the latter can be elevated and thereby compress the spring G until the upward elastic pressure of the latter counterbalances the entire weight of the disk A and screw H only be used to adjust relativelyv the walls of the chamber of a given size. This set screw H is also for changing the size of the chamber to accommodate the latter to a desired size of loaf, as, for example, a loaf weighing one. pound, or aloaf weighing two pounds, etc., becauseI have provided that the wall of the shell E shall extend beyond the wall A, A, the chamber S is at all times a closed one, no matter what be the size of the loaf or roll, so long as the latter is within the limits of the machine.

axial center B, and the disk A and its parts A, A A will revolve at a rate faster than that of the disk C and its said parts- The portions or lumps of dough are one after another dropped into the machine through the inlet T. Thus each lump, in succession, enters the chamber S. After entering this chamber S, each lump is carried, along in said chamber. The lump immediately assumes the shape of the chamber in cross section, viz.: a pear shape "W, substantially as shown in Fig. 5. The lump is rolled along betweenthe inclined bottom 0 of the chamber S and the inclined top A of the chamber.

I have ascertained that in case all of-the sides of the chamber, except the parts 0 C and C were stationary, the roll will not be properly rolled or kneaded, whereas by causing two walls out of the, three Walls of the chamber to rotate, the dough is properly formed into the desired shape, and being duly worked and rolled is delivered-from the chute V in proper condition to be baked.

The skin formed upon the roll is not broken, and the doughy'mass is caused to be more compact and rendered more dense by the operation of the machine. I

When the roll is delivered from the ma chine at the chute V, it is compact, has a uniform and proper density, and has a proper and unbroken skin. Its shape is approximately that shown in Fig. 5. But this shapecan be somewhat altered by pressing it, viz.: by pressing its small end toward the opposite. one.

In practice, the delivery chute is three quarters of a-circle from the hopper T. As a result, the dough lumps travel three quarters of a circle while being made into rolls of the kind aforesaid.

In Figs. 1 and 2, the delivery chute V is shown by solid lines at the opposite side of the circle from where the hopper T is. This is so shown to illustrate, in a single figure, viz.: Fig. 1, which is a section of Fig. 2, the construction and shape of the hopper end of the chute.

The preferred locationof the hopper and the delivery chute relatively. to one another is shown in Fig. 4 and by dotted lines at V, Fig. 1. The lump of dough travels around in the chamber S and along the wall E for the distance of three quarters of a circle, namely: two hundred and seventy degrees, measured along the said annular'wall.

When for any reason, it becomes desirable or necessary to have the disks A, C and I E vertical, the machine isthenpreferably constructed as shownin Figs. 3 and 4. In

this case, the'shaft B is'horizontal. It is" fixed vas hereinbefore mentioned, concen-- 'tricall y to the frame, at the art A of the 1 disk A provided as hereinbe ore mentioned with the parts A A and A. In this modification, the disk. A and its partsflare stationary and are supportedon a suitable frame-work, one form of which is shown and consists of the-ribs d, R, R, connected to the disk A, and the legs R extending therefrom to the base or-foundation plate- R". The disk C, with' its parts C, C,"C"is mounted on and fixed to a sleeve D eme bracing the shaft B and turning thereon. The disk E, with its parts'E and E isfixed on a sleeve E, which embraces the sleeve D and rotates u on it. In this construction, the gear Wheel B is concentrically fixed on the sleeve D, and the gear wheel D is concentrically fixed on the sleeve E.

The shaft F is present and carries gear i wheel F engaging the gear wheel I) for rotating the disk E with its parts E E". This shaft F also carries the gear wheel F 2 which engages the gear wheel B fixed on the sleeve D, which whenrotated, rotates the disk with its said parts. This shaft. F is supported preferably by the support E, which is extended upward and serves as a bearing E for the sleeve Eh. The shaft is also supported by the support E,

which is extended upward and provides abearin E for the end of the shaft B.

It'w1ll be understood, as has already been i} intimated in the case of the description of the mechanism of Figs. 1 and 2, that instead of cog wheels, belt mechanism or. the like may be used.

A. convenient inter-bearing for the shaft B, in combination with the bearing E is the bushing B embracing this shaft B, and

located within the bearing E". That end of this bushing B which faces toward the chamber S is preferably provided with a flange B which the better affords an abutment against which one end of the coiled spring G may press. Theother end of this soring presses against the sleeve D. This spring G is coiled around the shaft B. The

function of this spring G is much the same here as it is in the mechanism of Fig. 2.

lVhile the spring here is not called upon to sustain the weight of a disk with its parts as it is in the mechanism of Fig. 2, nevertheless it elastically yields to the pressure of the dough-lump as the latter is being formed into a roll, and yet causes enough pressure against the dough as the latter is' rolled Within the chamber, to cause it to be thoroughly compacted, and symmetrically formed and rolled, no matter what its varying size.

The bushing B 'has an-exterior screw thread, which engages-a female thread on the inner surface of the cylindrical bearing By rotating this bushing B and ad-.

E vanoing it toward the disk C, the flange G is advanced and the chamber S diminished in size. By rotating this bushing B in an o posite direction, opportunity isgiven for t e disk G and flange C? to recede, and thus to enlarge the chamber. Preferably. a

lock nut is present. This'screw threaded bushing B and the lock nut. B acts the same as the set screw H in Fig. 2. As in the case of the mechanism of Fig. 2, if the dough for the rollor loaf isof a uniform and unvarying size, the spring G in the mechanism of Fig. 3 may be dispensed with. The. operation of the mechanism of Fig. 3.

doesiiot'difi'er in results from that of the mechanism shownin Fig. '2. As regards the movements of the parts of the chamber S, While Fig. 2, the flange C and the flanges A A rotate andthe flange E is stationary: on the other hand,in-Fig. 3-, the flange E and the flange C rotate andthe flange A", A is stationary. In both cases,

the disk C, with its parts C and C, is the rapid mover, androtates more rapidly than the other rotating disk or part.

It will be noted that the function of the spring G is to advance a movable wall and to contract the, chamber, when a piece of dough is too small for the chamber as it was. It is to be further noted that the feature of construction, iii which one part of the chamber telescopes with another and can be set for variations of sizes of dough,

can. be employed, and the speed of rotation of the two rotatable portions of the chamberbe'varied, either by making one of said rotatable portions of the chamber rotate faster than the other inthe same direction, or by making the said rotatable portions of the chamber rotate in opposite directions. Such opposite rotation can be'readily accomplished by twisting a belt where belt phragmatic parts being omitted for light ness, I desire that it be understood throughout the specification and claims that the term disk shall includesuch skeleton frame. What I claim as new, and desire to secure by Letters Patent, is:-'
